(a) *POA&M.* For purposes of achieving a Conditional CMMC Status, an OSA is only permitted to have a POA&M for select requirements scored as NOT MET during the CMMC assessment and only under the following conditions:
(1) *Level 1 self-assessment.* A POA&M is not permitted at any time for Level 1 self-assessments.
(2) *Level 2 self-assessment and Level 2 certification assessment.* An OSA is only permitted to achieve the CMMC Status of Conditional Level 2 (Self) or Conditional Level 2 (C3PAO), as appropriate, if all the following conditions are met:
(i) The assessment score divided by the total number of CMMC Level 2 security requirements is greater than or equal to 0.8;
(ii) None of the security requirements included in the POA&M have a point value of greater than 1 as specified in the CMMC Scoring Methodology set forth in § 170.24, except SC.L2-3.13.11 CUI Encryption may be included on a POA&M if encryption is employed but it is not FIPS-validated, which would result in a point value of 3; and
(iii) None of the following security requirements are included in the POA&M:
(A) AC.L2-3.1.20 External Connections (CUI Data).
(B) AC.L2-3.1.22 Control Public Information (CUI Data).

(ii) The POA&M does not include any of following security requirements:
(A) IR.L3-3.6.1e Security Operations Center.
(B) IR.L3-3.6.2e Cyber Incident Response Team.
(C) RA.L3-3.11.1e Threat-Informed Risk Assessment.

(b) *POA&M closeout assessment.* A POA&M closeout assessment is a CMMC assessment that assesses only the NOT MET requirements that were identified with POA&M in the initial assessment. The closing of a POA&M must be confirmed by a POA&M closeout assessment within 180-days of the Conditional CMMC Status Date. If the POA&M is not successfully closed out within the 180-day timeframe, the Conditional CMMC Status for the information system will expire.
(1) *Level 2 self-assessment.* For a Level 2 self-assessment, the POA&M closeout self-assessment shall be performed by the OSA in the same manner as the initial self-assessment.
(2) *Level 2 certification assessment.* For Level 2 certification assessment, the POA&M closeout certification assessment must be performed by an authorized or accredited C3PAO.
(3) *Level 3 certification assessment.* For Level 3 certification assessment, DCMA DIBCAC will perform the POA&M closeout certification assessment.
